In summer 2021, the Future Circular Collider Feasibility Study was launched.
The FCC-ee builds on 60 years of operating colliding beam storage rings. The design is robust and will provide high luminosity over the desired centre-of-mass energy range from 90 to 365 GeV. [...]

The Superconducting Shield (SuShi) Septum Magnet Prototype
/ Barna, D (Wigner RCP, Budapest ; Miskolc U.) ; Borburgh, J (CERN) ; Atanasov, M (CERN) ; Kirby, G (CERN) ; Giunchi, G (Unlisted, IT) ; Kárpáti, V (Miskolc U.) ; Szűcs, M (Miskolc U.) ; Szabó, G (Miskolc U.) ; Mertinger, V (Miskolc U.)
The Future Circular Collider proton-proton ring would require a high-field septum magnet with a blade as thin as possible for the extraction of the 50 TeV proton beam from the ring. One of the two baseline concepts in the conceptual design report is the “superconducting shield” (nicknamed as SuShi) septum, utilizing a zero field cooled, passive superconducting shield in order to create a zero-field channel for the circulating beam inside the bore of a 3 Tesla canted cosine theta (CCT) type superconducting magnet.

Evaluation of the nonlinear surface resistance of REBCO coated conductors for their use in the FCC-hh beam screen
/ Krkotić, P (CELLS - ALBA, LLS ; Barcelona, Polytechnic U.) ; Romanov, A (Barcelona, Autonoma U.) ; Tagdulang, N (CELLS - ALBA, LLS ; Barcelona, Polytechnic U.) ; Telles, G (Barcelona, Autonoma U.) ; Puig, T (Barcelona, Autonoma U.) ; Gutierrez, J (Barcelona, IFAE) ; Granados, X (Barcelona, Autonoma U.) ; Calatroni, S (CERN) ; Perez, F (CELLS - ALBA, LLS) ; Pont, M (CELLS - ALBA, LLS) et al.
To assess the feasibility of using high-temperature superconductors for the beam screens of future circular colliders, we have undertaken a study of the power dependence of the microwave surface resistance in state-of-the-art REBCO coated conductors at about 8 GHz and 50 K. We have employed a dielectric resonator to produce radio-frequency (RF) electromagnetic fields on the surface of the coated conductors having amplitudes similar to those generated by proton bunches circulating in the vacuum chamber of the proposed future circular collider Hadron-Hadron (FCC-hh) at CERN We show that surface resistances in REBCO coated conductors without artificial pinning centers are more affected by a RF magnetic field than those containing nano-inclusions.
